Obviously most allied fighters could boom and zoom vs the Japanese aircraft, history proves that. If I wanted something to TRY and turn and burn with the Japanese fighters, it would have to be a Spitfire. I think with any of the top U.S. fighters, turn and burn would not be a good idea.

I think the Corsair vs 109G would be altitude dependant. Up high, 25 thousand plus, the Messerschmitt would be a big problem. Lower than that and I think the Corsair would have every advantage except climb, but it would be only a little behind.

Now I know someone will post a graph showing I'm wrong, but thats what I think just looking at the scenario.

Well, the P-51 seemed to be able to hold its own in a turning fight with the '109. And as the Corsair is a better dogfighter than the Mustang (at least below 25,000ft) it seems likely that the Corsair could do at least as well.
